Referring to the drawings in which similar reference characters represent like parts thruout, a frame I0 is provided which may be mounted on any suitable base H such as a table, platform or the like and held in position thereon by bolt, screw members l2 disposed at spaced intervals alongside the edge of frame III as shown and extending into the base. Said frame may be of any suitable length or width andis pref- 15 erably made of metal.

Extending upward at one end portion of frame I0 is a supporting member l3 onto which are journalled parallel shaft members l4 and I5 Said supporting member may be integral with the frame or may be an easily attachable strut adapted to serve the purpose for which intended. The member I3 is retained in fixed position on frame ill by meansvof a pair of screw bolts l6 and I1 respectively each extending thru the opposite edges of the adjacent end of the member into frame l0. It is to be noted that the shaft members are substantially free of friction and can easily be rotated.

Shaft member l4 extends over the frame Ill and is adapted to retain'a roller l8 onto which is wound a tape I 9 of suitable receptive material. Said roller I8 is provided with a set screw extending thru one side of the roller to make contact with shaft member and remain fixed thereto. Shaft member I5 is also provided with a roller 2| adapted to carry a roll of thermo plastic tape 22 having a covering of waxed paper 23 or like material of corresponding width. It is to be noted that said roller 2| is also provided with a set screw 24 adaptedto retain the-roller in fixed position on the shaft. T

It is to be noted that the rolls are in parallel position whereby the strip of fabric, thermoplastic material and waxed paper are super-, imposed over each other as shownin Fig. 4 of the drawings preparatory to treatment.

Disposed under shaftlS is. an L shaped angle bar 25 fixed to member 13 by a bolt and screw, 26. A curved guide plate 21 is; mounted .onto the short arm of bar-25 extending over theframe i0. Said; plate'is also adjustable thereonfjby means of threaded screw 28, extendingfrom the I guide plate 2'! and nut 29.

Fixed to frame In is a, hot plate 39 which extends along a major portion of the length of the frame. Said plate 30 is retained in position on the frame by means of a plurality of screws 3| disposed at spaced desired intervals along the marginal edges of the plate. It is to be noted that the plate is of a width preferably less than that of the frame and may be of any highly polished metallic surface. Furthermore, intermediate the. frame and base plate is a plurality of collars 32 for keeping the plate in raised position on the frame. Said collars are made preferably of insulating material and accommodate the screws 3|. The hot plate 39 is provided with an electrical heating unit which is in connection with a source of electricity by means of conductors 33 and 34 on the under side of said plate. It is to be noted that plate 30 may be heated along its entire length to any desired temperature depending upon the degree of heat necessary to weld the receptive material and thermoplastic tape as will be hereinafter described.

At the other end of frame H1 is another vertically extending supporting member 35 fixed thereto by means of bolts 36 and 31, respectively. Said member 35 is parallel with supporting member l3 and is disposed at the opposite end of the frame, whereby plate 30 is disposed intermediate said members.

Supporting member 35 is provided with a cylinder 39 whose shaft 39 is journalled thereto.

Said cylinder is disposed on the shaft so as to have part of its periphery in line with the surface of plate 30 as shown in Fig. l of the drawings. 7

Cylinder 38 is provided with a surface of re silient material 40. It is to be noted that cylinder 2-8 is provided with a geared peripheral extension 4|. Said support 35 is further provided with a drive shaft 42 onto one end of which is a pulley wheel 43 for accommodating drive belt 44 in connection with a shaft 45 of drive motor 46. Set in from the wheel 43 is a small drive gear 41 on shaft 45 for connection with a gear 48 which is mounted on an idling shaft 49. The other end of said shaft 49 is provided with a gear 50 in engagement with gear 4| of cylinder 38 for actuating the same.

Adapted to contact cylinder 38 is a friction cylinder for retaining resultant tape 52 under tension when the device is in operation. It is to be' noted that cylinder 5| rotates counter to cylinder 38 and is provided with arms 53 and 54 extending perpendicularly from the center of said cylinder. Said arms are journalled to shaft 45 to permit swinging of the cylinder 5| there on prior to adjustment of tape 52 on cylinders 39 and 5|.

Support 35 is further provided with a shaft member 55 journalled thereto and extending at right angles therefrom. The shaft member has a collecting roller 56 fixed thereto by means of a set screw 51 disposed in one of the faces of the roller and making contact with shaft 55.

It is to be noted that when motor 49 is in operation the receptive material I9, thermoplastic tape 22, and waxed paper 23 are in overlay position under tension as shown in Fig. 4, and guided onto plate 30 by means of guide 21 and cylinder, to form a resultant tape 52 in which the cloth and thermoplastic tape are fused together while being drawn over plate 39.

In order to retain the overlay tape, cloth and paper in relatively superposed fiat position on plate 39, while being drawn along thereon, there is provided an overlay platform 58 of channeled metal slidably mounted on a plurality of guide shafts 59 and 69. Said shafts are fixed at one end to frame l9 by means of upright members 9| and 92 respectively, upwardly extending from the frame. It is to be noted that said guide shafts are of sufficient length to extend the width of said frame I to permit proper positioning of the platform. Said shafts 59 and 99 are furthermore provided at one end with stop collars 93 and 64 for properly fitting platform 59 over plate 39.

Said platform 59 is provided with a pair of channel bars 95 and 69 respectively, pivotally mounted intermediate the vertical walls 61 and 99 respectively of the platform onto shafts 59 and 99 respectively. Channel bar 65 is pivoted to platform walls 61 and 99 by means of a pivot rod 99 and has pivotally connected an L shaped member 10.

Said handle is pivotally connected to the channel bar at the intersection of the long and short arms 1| and 12 respectively, while the end of the short arm 12 is in pivotal connection with a collar rod 13. Interconnecting rod 13 and channel bar 96 are an adjustable shaft member 14 and an extension block which in turn is pivoted to a pin 19. Said channel bar 99 is pivoted to the walls 91 and 99 of platform 59 by means of pin 19.

Collar rod 13 is provided with a stop 18 for retaining a spring 19 under tension on the rod.

It is to be noted that shaft 14 is adjustable relatively of rod 13 to obtain the proper tension of spring 19. It is to be further noted that the handle 19 when operated performs a toggle action whereby platform 58 may be lowered directly over plate 30 or raised when the device is in operation.

Supporting member 35 is further provided intermediate gear roller 56 and shaft 42 with an extension rod 80 having a cross member 8| for keeping tape 52 under tension after it passes cylinder 5| and also to prevent said cylinder from being raised out of position as shown in Fig. 1.

In the operation of the presently disclosed preferred embodiment, a roll of cloth l9 or any other suitable material of any suitable width adapted for adhesion is brought into position with another roll containing a thermoplastic cement tape 22 and a "glassine" or impervious paper 23, forming a triple layered product or tape 52 as shown in Fig. 4. Said multi-layered tape is then passed over a space, sufficiently large therefor without preventing movement of the same, formed by the heated plate 30 and overlaying platform 59. As said layers pass over the plate the cement tape 22 becomes sufficiently soft to penetrate the layer of material l9 under pressure and form a film thereon. By the time said layers reach the end of the plate the tape 22 and material |9 are sufficiently welded to permit rolling, whereupon they pass over cylinder 49 then equalizing cylinder 5| over cross member 9| and onto roller 59. It is to be noted that the paper strip 23 may be either removed before resultant tape 52 is collected on roller 56 or it may be rolled thereon to prevent the film of cement tape 22 from adhering to the uncoated surface of the receptive material I9.

By the present invention a continuous operation of adhering a film of thermoplastic cementitious material onto a receptive surface is effected. The width of the rolls, of the heated plate, of the cylinders and platform may be of any desirable no crumpling or wrinkling of surfaces during the adhesion operation. A product obtained as shown in Fig. 4 is adapted for use on labels, cloth, paper or other suitable receptive material to form an interlining or covering with other desirable materials. I

While one preferred embodiment of the present invention has been described in detail in connection with the accompanying drawings, it is understood and to be noted that various changes as to form, use of materials and arrangement of parts may be made without departing from the spirit and scope of the present invention as set forth in the appended claims.
